SPECIFICATION forming part of Letters Patent No. 338,247, dated March '23, 1886.

Application filed November 30, 1885. Serial No. 184,324. (No mode .TO aZZ whom it may concern.-

Be it known that I,- JAMES C. BRoYLEs, a citizen of the United States, residing at Tupelo, in thecounty of Lee, State of Mississippi, have invented certain new and useful Improvements in Breech-Loading FireArms, of which the following is a specification, reference being had therein to the accompanying drawings.

. My invention relates to breech-loading firearms having an internal hammer; and it con- Y sists in the construction and arrangement of the parts which will be more fully hereinafter described, and definitely pointed out in the claims.

Heretofore firearms of this class have generally been constructed with a hammer for.

breech-loading fire-arm with a lock having a single internal hammer, which is adapted to operate the firing-pins of a single or double barreled gun by means of a suitable revolving firing-center situated on the upper end of the V hammer, the mechanism for actuating said hammer being simple, efficient, and durable.

in its construction,casily operated, and readily understood. I attain these objects by the mechanism illustrated in the accompanying drawings, wherein like letters of reference indicate similar parts in the several views, and in which-- I Figure 1 is a side elevation of a doublebarreled breech-loading gun with the casing of the lock removed, and illustrating the two positions of the look by positive and dotted lines. Fig.2 is a longitudinal vertical section of the hammer, illustrating the two parts and their internal construction. Fig. 3 is a sectional and top plan view of the locking device for securing or releasing the barrel and opening or closing the breech.

The drawings illustrate the look as applied to a double-barreled breech-loading gun, but it is obvious that it is adapted to be used in connection with any other style of fire-arms of this class with equal efficiency.

Aindicates the breech-frame of an ordinary breechloading fire-arm which has bearingframes A A for the sliding bolt. The sliding bolt consists of two parts, the round bolt B, secured to or cast integral with the head B. and the square bolt B, formedwith the said head B. The bolts B and B' are mounted in the bearingframes A A, in which they have a longitudinal sliding movement slightly on the incline. The portion B of the double sliding bolt is surrounded by a coiled spring, B, which rests against the bearing-flames A at each of its ends, a washer-plate being pro Vi'ded in the forward frame A, against which the spring rests, and keeps it from interfering with the sliding movement of that part of the bolt by slipping into the recess or aperture in which the said bolt enters. This plate also prevents the hammer from being pressed upon the cap by the power of the spring 13 when at rest. The bolt B extends through the rear bearing-frame A a short distance, and has free backward and forward movement therein. The portion B of the sliding bolt is formed integral with the head B, and is rectangular in shape its entire length, except a short distance from the rear bearing-frame A, where it is rounded, so as to more easily move in the said bearing-frame. A slot, b", is formed in this portion B of the bolt, which extends through the said portion and forms a small rectangular opening, I). This slot 1) extends rearwardly to the point N, where a shoulder is formed for purposes which will be hereinafter described.

As heretofore described,the forward part of the sliding bolt is formed with a head, B. This head B has a slot cut in its forward portion, in which one end of a link, C, is hinged, as at c. The upper and lower parts of this head B are cut away to form a point, If, below which the link 0 is hinged.

Formed integral with the breech-frame A, andin the forward lower portion thereof, is a metallic lug, I), which is recessed, as at d, in its rear portion. point e is a hammer, E, which is constructed of such shape as to conform to and notinterfere with any of the other working parts of thelock' with which it may come in contact when set for firing. As illustrated in Fig. 2, this hammer is formed with a recess, 0, which strad- Hinged to this lug D at the LII dles the lug D. The other end of the link is hinged in this recess 6, and has free'movement therein.

In a recess, e, formed in the upper portion of the hammerE, aratchet-wheel, E, is mounted on one end of a shaft, 0. This shaft extends through the upper part of the hammer E to the outside thereof, and has mountedon its end a centering firing-disk, F. This centering firing-disk F has a series of nipples, f, cast integral with its face. In the drawings three nipples are represented, but as many may be used as are necessary.

At the point (1 in the lug D a wire spring, E", is pi voted, which extends upwardly through the hammer E, and has movement in a concave recess, 6, formed therein. It then passes through a hole, 6", bored in the upper portion of the hammer E, its point engaging with the teeth of the ratchet-wheel E, which it turns, and therewith the centering firing-disk F is turned, alternately presenting one of the nipples f, so that itwill strike one of the firingin which it operates.

pins. Seated in the upper part of the hammer E, and directly behind the firing-disk F, is a small coiled spring, f, which acts as a cushion for said firing-disk F, and prevents injury to the hammer and its parts by the re' bound of the disk F when it strikes the firingpin, and also acts to keep the said disk F conlined in its proper place and prevent it from.

being drawn back by the retraction of the spring E".

To the point a of the forward bearingframe A a portion of a combined trigger and sear is pivoted. The sear portion G has a recess, g, formed near its forward extremity, which engages with a spring, D, the other end resting in a recess, d, formed in the lug D. Another recess, 9 is formed in the sear G a short distance below the recess for the purpose of allowing said sear to have an easy motion, and not be caught or checked by the lower part of the breech-frame, through a slot The point 9" of the sear has a dog, G, pivoted and operating in a slot formed therein, said dog being actuated and held in a raised position by a spring, G secured to the under side of said dog, its other or free end engaging with the lower portion of the breech-frame A.

In Fig. 3 a section and plan view of a top snap-lever is illustrated. This lever consists of a top plate, H, which has a suitable milled end, h. A screw, h, passes through the center of the forward part of said plate and down through the central portion, h of a springactuated sliding bolt situated and having free movement in a recess, a formed in the top portion of the breech-frame A. The portion h is squarein form, and a bolt, h, extends horizontally outward from the front portion into a recess, a, into which a projection on the barrel fits, and the portion If of the bolt fits into an aperture formed in the projection.

Extending rearwardl y from the square por tion It is another bolt, h, which'is encircled and actuated by a spiral spring, h.

To one side of the screw h a fulcrum-pin, h, passes through the plate H, said pin being situated near one of the outer corners of the said plate. 13y forcing the plate H to oneside against the pin h by means of the milled end h the bolt h is drawn backward by means of the screw h being turned, said bolt pressing against the force of the spring k This device allows the barrels to lock themselves automatically, and is effective and durable in its operation and construction.

The operation of this device is simple, being shown in full and dotted lines in Fig. 1, and is as follows: It being desired to discharge the contents of one of the barrels of the gun, the combined sear and trigger G is drawn back until the point of the pivoted dog G engages with the shoulder b of the slot 1) in the lower portion, 13*, of the sliding bolt. and sear G are drawn around until the rear point of the sear reaches the position shown in dotted lines. While the sear has been turning the dog G pushes against the shoulder b", forcing the bolts B and 1B and head B backward. The head B through the medium of thelink O in being drawn rearwardly draws the hammer E back also until it reaches the position indicated by dotted lines,resting upon the upper part of the head B. The recess 9 in the upper portion of the combined trigger and sear G engages with the end of the spring D, and while the said searhas been turned on its pivot a the said recessed portion 9 has continually held the spring D and pressed it down and holds it when in the position shown in dotted lines. WVhen the hammer Eis drawn back or in cocked position for firing, as shown, it is held in this position by the pivots a? and g and the shoulder I) being practically in line or on a dead-center. A little further pressure of thetrigger releases the point of the dog G -from against the shoulder b, and the dog G drops down out of-the way of the bolt B", which is shot forward by the action of the spring B and the gun is discharged. The spring D brings the combined trigger and sear G back to its normal position, ready for another operation. When the hammer Eis drawn back,the spring E engages with a tooth of the ratchet-wheel E and shoves it around, presenting a nipple, f, of the disk F, so that it will strike one of the firing-pins of the barrels of the gun, and as the hammer E is shot forward the spring E is disengaged from the tooth of the ratchet-wheel E. This movement is so timed and the nipples f so arranged that the firing of the barrels may be desirably controlled, and prevent the discharge of a barrel not intended to be discharged or a miss striking of either of the firing-pins.

It is obvious that many minor details in the construction and arrangement of the parts could be made and substituted for those shown and described without in the least departing from the nature and principle of my invention. c
